 ## What is Wasm64?
 
 The Wasm64 target allows canisters to:
 - Access larger memory spaces (up to 6GiB, compared to the 4GiB limit of Wasm32)
 - Use 64-bit memory addressing
 
-This example always builds for Wasm64 using Rust's nightly toolchain and the `-Z build-std` feature.
+This example uses the `build.sh` script to build for Wasm64 using Rust's nightly toolchain and the `-Z build-std` feature.

+When viewing this project in ICP Ninja, you can deploy it directly to the mainnet for free by clicking "Deploy" in the upper right corner. Open this project in ICP Ninja:
 
-- `Cargo.toml`, which defines the crate that will form the backend.
-- `lib.rs`, which contains the actual smart contract, and exports its interface.
-- The `build.sh` script that automatically builds for Wasm64 using the nightly toolchain.

 ## Build and deploy from the command-line
 
-To build and deploy this Wasm64 example locally, follow the instructions in the `BUILD.md` file.
+### 1. [Download and install the IC SDK.](https://internetcomputer.org/docs/building-apps/getting-started/install)
+
+### 2. Download your project from ICP Ninja using the 'Download files' button on the upper left corner, or [clone the GitHub examples repository.](https://github.com/dfinity/examples/)
+
+### 3. Navigate into the project's directory.
+
+### 4. Run `dfx start --background --clean && dfx deploy` to deploy the project to your local environment. 
+
+## Security considerations and best practices
 
-The build process will automatically:
-1. Install the Rust nightly toolchain if needed.
-2. Add the `rust-src` component for `build-std`.
-3. Build the canister for the `wasm64-unknown-unknown` target.
-4. Extract the Candid interface.
-5. Prepare the Wasm file for deployment.
+If you base your application on this example, it is recommended that you familiarize yourself with and adhere to the [security best practices](https://internetcomputer.org/docs/building-apps/security/overview) for developing on ICP. This example may not implement all the best practices.
